As evidence-based prevention programs move from the research environment to the real world, the fidelity of their implementation is jeopardized. In our national study of middle school-based substance use prevention practice (SSUPPS) (N=1905), we showed that approximately one-quarter of lead staff who taught substance use prevention are using an evidence-based curriculum, such as Project ALERT and Life-Skills Training, indicating substantial dissemination of these programs. In this paper, we assess the extent to which evidence-based curricula are being implemented as intended, and examine school and teacher characteristics that may be associated with implementation fidelity. To assess implementation, we asked providers a series of questions concerning the content they emphasized (e.g., refusal skills, social influences knowledge) and the delivery methods they used (e.g., role plays, lectures). We compared their responses against standards for best practices in substance use prevention curriculum content and delivery methods that we derived from the seminal meta-analytic studies of Tobler and colleagues. Results showed that fewer than one-third met these standards; although low, the percentage is significantly higher than for those providers not teaching an evidence-based curriculum. Both school and teacher characteristics were significantly associated with meeting the standards. Most notably, providers who were recently trained, reported comfort in using interactive delivery methods, and were in a school with a positive climate were more likely to implement curricula in accordance with these standards. Results suggest that teachers and schools need resources and support if evidence-based programs are to be implemented as intended and thus to achieve maximal effectiveness.
